tom_calc_exptime

calculates the exposure time according to the used exposure scheme

Syntax

[exp_time]=tom_calc_exptime(time,angle,option,flag)

Input:
time :input time
angle :actual tiltangle
option :scheme used for calculation (const,cosine (assuming a slab geometry of the object) or exp)
flag :direction (inverse,normal)
 
Output  
exp_time :exposure time

 

Description

tom_calc_exptime calculates the exposure according to given exposure
scheme. The calculation can be done in both directions
... with flag inverse you get the basetime for given exptime.

Examples

exp_time=tom_calc_exptime(0.5,60,'cosine','normal') ==> exp_time = 1.0
exp_time=tom_calc_exptime(0.5,60,'cosine','inverse') ==> exp_time = 0.25
tom_calc_exptime(State.CCD.ExposureBaseTime,get(COMS.TEM.Stage.Position,'A').*180./pi,State.CCD.ExposureTimeScheme,'normal')
tom_calc_exptime(State.CCD.ExposureBaseTime,get(COMS.TEM.Stage.Position,'A').*180./pi,State.CCD.ExposureTimeScheme,'inverse')
